According to http://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.9[the Java Language Specification-8.9]:

____
Nested enum types are implicitly ``++static++``.
____


So there's no need to declare them ``++static++`` explicitly.

== Noncompliant Code Example

----
public class Flower {
  static enum Color { // Noncompliant; static is redundant here
    RED, YELLOW, BLUE, ORANGE
  }

  // ...
}
----

== Compliant Solution

----
public class Flower {
  enum Color { // Compliant
    RED, YELLOW, BLUE, ORANGE
  }

  // ...
}
----
